PVR EU HWT 47-67
PVR EU HWT 47-67 is intended for industrial vacuum duties with elevated water-vapour loads where condensation control is a key selection factor. The EU 47 HWT and EU 67 HWT group uses PVR rotary-vane technology to provide a defined relationship between pumping speed and operating pressure, which is central to equipment sizing. For engineers and maintenance teams, the key decision is to match the required pressure, gas load, operating frequency and vapour content to the correct version rather than select on flow alone.An oversized circuit and continuously active gas ballast are used to limit condensation when larger quantities of vapour are pumped. Compact EU 47M HWT and EU 67M HWT versions are also available.Verified technical data for PVR EU HWT 47-67 includes 50 and 67 m³/h at 50 Hz (56 and 80 m³/h at 60 Hz) and an ultimate pressure of ≤0.8 mbar with gas ballast. PVR specifies 0.8–850 mbar absolute. The published range also includes water-vapour pumping capacity of 2 and 3 kg/h at 50 Hz. These datapoints provide a selection basis, but the final operating point must be checked against the exact pump version and process conditions.Oil-lubricated rotary vane construction combines continuous lubrication with defined gas handling and serviceable components. Features such as check valves, oil-mist separation and gas ballast where fitted help protect restart behaviour, exhaust cleanliness and vapour handling, which can reduce avoidable maintenance events. AxFlow can support product selection, service and spare parts for PVR EU HWT 47-67; planned maintenance and correct variant selection help control downtime risk, process continuity and total cost of ownership.
